Beetles soaked in alcohol, above 75 degrees. Soak for half a month to a month. Take it out. Use toothpicks or pins to shape the legs of insects on the foam board. It's fixed. Dry. At this point, the worm has been dehydrated by alcohol, and there is only alcohol in the worm. Just drying alcohol. Cool for a few days. Using a hair dryer can speed up the speed. When the bug is dry, stick it on the glass box, label it and put mothballs on it. Cover the glass. Let's call it a day.
